IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 213,803, dated April 1, 1879 application led August 20, 1878.

To all whom it may concern:

Be it known that I, HENRY BAER, of Fond du Lac, Wisconsin, have invented a new and useful Improvement in Spring Bed-Bottoms, of which the following is a clear, full, and exact description, reference being had to the accompanying drawings, making a part of this specilication, in which- Figure 1 is a plan view of my improved bedbottom. Fig. 2 is an end view. Fig. 3 is a bottom View. Fig. et is a longitudinal section through 011e of the side bars.

Toenable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the drawings, A A are two longitudinal spring-bars, having elongated slots b at their ends, and mounted upon suitable transverse supports E E, which will rest upon the side rail of the bedstead. A' A' are longitudinal top bars, connected to the bars A A by means of spool-shaped pieces C G and headed pins or bolts b', which pass through perforations in the top bars and spool-shaped pieces, and through the elongated slots b in the bars A A, and are held in place by nuts or other suitable means. Between the upper and lower spring-bars are secured, in a suitable manner, spiral springs D, which serve to keep the longitudinal bars apart, and give additional elas- ,ticity to the bed-bottom. F is a lattice-work of thin slats, which rest upon the bars A' A', and are secured thereto by means of rivets f,

as shown. The bolts attach the spool-shaped pieces rigidly to the upper bars, A' A', consequently, when said upper bars are straightened by compression, said spool-shaped pieces and bolts are forced farther apart, and to ac commodate this movement apart of the bolts the orifices in the lower bars are made in the shape of longitudinal slots.

I am aware that longitudinal bars slotted and connected together at their ends, and having interposed springs to keep them apart at points intermediate thereto, is old; nor do I claim a lattice covering for a bed-bottom;
